In an integrated, dual disorder treatment program delivered at two sites, t
he authors address numerous barriers to delivering services to dually diagn
osed consumers and employ a set of multidimensional indicators to assess ou
tcome. Consumers who received services through the well-implemented, integr
ated services program for 12 months were functioning better in the communit
y. There was a cost shifting from mental health to drug and alcohol service
s, as well as a one-third increase in the total costs of care by the end of
the first year of treatment. Program implementation issues are described a
nd the clinical management implications for more effectively serving dually
diagnosed consumers through integrated treatment programs are discussed.
